Hi Alfredo,
I tested with latest pfring from github but still packets are segregated to
different applications.
After your latest change, We need to use cluster_per_flow_2_tuple only
right to segregate traffic on outer ip addresses ?
Should we load pfring module with enable_frag_coherence=1? I ha
Thanks Alfredo for an update.
I will update you once merge with latest
PFRing.

Gautam

Derek,
this problem is odd because we run continue tests with docker (see
https://github.com/ntop/packager) and we have never seen this problem.
I have now analysed the use on centos 6.8 and this is what I have

Hi Luca,
Yes, although I fully removed n2disk and pfring before reinstalling everything
from RPMs (via yum).
Thanks,
Derek

Hi Alfredo,
I updated, but now I've run into a different problem. It looks like the new
version of n2disk10g requires glibc 2.14? Was that just changed in this
version? I'm on RHEL 6 and have 2.12:
$ sudo /usr/local/bin/n2disk10g /etc/n2disk/n2disk-eth5.conf
/usr/local/bin/n2disk10g: /lib64/l
Hi Derek
I tought I updated you on this, but it seems it is not the case,
could you try using -R with latest release?
Best Regards

Hi Gautam
your traffic is GTP traffic and the hash was computed on the inner headers when
present,
I did change the behaviour computing the hash on the outer header when using
cluster_per_flow_2_tuple, and introduced
new hash types cluster_per_inner_* for computing hash on inner header, when

Hi Gautam
could you provide a pcap we can use to reproduce this?

Hi,
We are using PFRING cluster feature and using cluster_2_tuple and 2
applications
are reading from same cluster id.
We have observed that the packets having same source and destination ip
addresses are getting distributed across 2 applications which has
completely tossed our logic as we are tr
